@Headhunter, you teach. What if you found out that someone you were teaching was out starting trouble so they could hurt people with the things you were teaching them?
I see little kids in their gis all the time. See them in their baseball uniforms too. Or dressed like a cowboy. More power to them.
I only ever cared what my students did. And only if they were of age. And if they dressed like a cowboy, they show should at least wear spurs.
